To alt whom it may concern a citizen of the United gtates, Newton, county of Jasper, lows, have invented certain new and useful l mpnovements in Bailing-Presses, of which the following is a'specification.

It is the object of the present invention to a baling press in which the severai operations are in a large measure automatic, and in which the succession of oper'aticns can be carried out continuously and at high speed.

More particularly the invention relates to a press having a reciprocating power driven plunger working in conjunction with a feeder for delivering hay or other material into the chamber, ere to be compressed by the plunger. The machine also includes wire-carrying needles which can pass through suitable slots in the plunger while it is at the end of its compression stroke, and which carry wire for binding the compressed hay. in the preferred embodiment of the present invention clutch mechanism residing at of improved construction is utilized for con trolling the movement of the wire-carrying themselves are of special shape and movable with a sufiicient motion to insure most advantageous feediug of wire and the least possible danger of wire breakage. Jlhe preferred embodiment also includes an improved wire-cutting mechanism and also control mechanism whereby the successive operations may be regulated and be made to follow one another in the proper sequence and at the proper time intervals automatically regulating the size of the bales and insuring tight and secure binding with the wires.

Figs. 19 and 20 showthe structure of the clutch or latch mechanism used to govern the movements of the wire-feeding mechanisin and of the wire twisting mechanism, changes in theposition of certain of the parts being indicated by dotted lines. Fig. 21 is an and elevation of the members used at the tail end oi-thc machine to regulate the cross section of the outlet and thereby to regulate the degree oi compression produced in the machine.

In the construction shown, the supporting frame work 1 of the press is mounted on wheels for ease in transportation. The main power shaft 2 mounted transversely to the foams work is provided with apower pulley 3 for connection to a suitable source of energy, such as a gas engine, and is also provided with a heavy. fiy-wheel d. The shaft 2 carries a inion 5 meshing with a large gear 6 fine upon a counter-shaft 7 arrangedtransverse to the machine frame and carried in suitable bracket bearings. The shaft 7 also carries pinions 8 and 9 which mesh permanently with large ear wheels IO'and 11 mounted to turn in unison and serving to drive the main plunger while also acting as a part or the tripping mechanism for the wire operating mechanism and the twisters. The latter function is attained through the presence on these wheels ofprodriving raclrand with its jecting side flanges numbered respectively 12 and 13, these flanges serving as cam sur faces and having openings or cut away portions suitably disposed to bring the wiring mechanism and v the twisting mechanism into play at the proper time with respect to the movement of the plunger and completion of the bale. n the twister side of the machine the flange or cagn face 13 has a single opening 14 of about the angular width and relative position indicated in Fig. 14:, but on the needle side'ot the machine, as shown in Figs. 2 and 17, there are two cut away portions 15 suitably spaced to time the action of the needle to the action of the plunger and of the twisters.

The large gears 10 and 11 are connected together near their periphery by a crosspin 19, to which is pivotally secured the plunger rod 20, the other end of which is connected to the plunger 21. When the gears 10 and 11 are rotated through the action of the belt connected driving engine, the plunger 21 will be reciprocated back and torth in the baling chamber and can be used to compress within that chamber the hay or other material fed in at the hopper on the top of the machine immediately above the path of the forwardlymcvingplunger.

The clutch mechanism mounted at the rear of the main frame 1 and used for controlling the action of the wiring mechanism and of the twisters comprises two latch mechanisms, one on either side of the main frame and both actuated from a common drive shaft, one of the mechanisms being arranged for operative connection with the' wire carrying needles and the other being arranged to operate the twisters after the needles have been swung around through 0 enings in the plunger to" completely inc ose with wire the hale just completed.

The clutch mechanism on the left-hand side of the machine includes a crank disk 22 for operating the twister rod, and the clutch mechanism on the ri ht hand side of the machine includes a crank disk 23 for operating the needle rod. These clutch mechanisms are essentially the same in construction, and the description of but one will suffice. Meshing withthe large gear 11 is a small gear 2d mounted on a counter-shaft 25 which rotates continuously and which serves as a power shaft which can be pe riodically connected up through clutches to either the needle mechanism or the twister mechanism, the connection to this continuously rotating shaft 25 being maintained only just long enough to produce in' each instance a one-half revolution of the crank disks 22 and 23, itbeing understood that these disks are operated in succession, disk 23 first throwin the needles through the plunger to comp etc. the loop of wire about the bale, then disk 22'moving to twist the cross arm 26 hearing inraaaa wire, anditliendisk 23 making another hali an Therevolutionto? withdraw the needles thread the machine for another bale. details of one of the clutch mechanisms is shown in Figs; 19 and 20. Mountedrigidly on the continuously rotating shaft25j-i's a a roller 27 J. at either end, these rollers being spaced away from the inner-face of the crank disk 22', but with a latch 28 so shaped that it can serve to establish driving connection between the rollers and the disk, thereby serving to connect the disk with the continuously rotating shaft 25 for such time as the latch 28 may remain in its extended or operative position with respect to the continuously moving rollers 27. The latch 28 has a lateral projectingshoulder 29 which serves as the strikmg face for the rollers 27 when the latch is in its outermost position; itlbeing understood that the latch is pivotally mounted at 30 and is provided with a suitable spring urging the lug 29 outward into the path of the moving rollers 27. The inner end of the latch is positioned to serve as a stop to limit the outward swin of the latch by striking against the shalt 25, as indicated in dotted lines in Figs. 19 and 20. A pair of vertically disposed arms 31 and 32 arranged on either side of the latch mechanism serve to control the position of the latch and thereby serve to govern the connection between the rollers 27 of the continuously swinging arm 26 and the cam disk 22. Arm 32 has a hook at its lower end for engagement with the front face of the latch 28 to hold the latch inward with its lug 29 out of thepath of the rollers 27 when no movement of the crank disk 22 is desired, said arm 32 being movable outward with a swinging motion to release the latch and allow it to swing outward as shown in dotted lines, Fig. 19, thereby putting the lug 29 in the path of a roller 27. The lower end of the arm 31 serves a similar function after the crank disk has swung around into the position shown in Fig. 20.

Arms 31 and 32 have horizontal extensions pinned together with a sliding connecting pin at 33, so that they move in unison. A projecting arm 34 rigidly connected with one of the arms bears on the cam face 13 of the main wheel 11, and, by dropping through the opening 14 in the cam face, serves to swing the arms 31 and 32 outward in unison. As a means for pulling the extension 34 down into contact with the cam face 13, there is provided a link 35 yieldingly connected to the extension 3d and pivotally connected with one arm of a bell crank 36 movable about an axis 37 and pivotally connected to a control rod 38 which extends along the side of the press, as shown in Figs. 1 and 14. T hisrod is curved downward at 39 and carries an upwardly extendwardly extending .will be rotated in a almanac ing link 40 having an adjusting turn buckle 41. The upper end of this link rests on a. lug 42 carried on top of the frame work of the machine. A lateral extension 43 on the supporting link engages the lug 42 under certain conditions, but can be pushed off to drop the front end of the control rod 38 when desired. The suspended position of the parts is shown in Fig. 1.

The coiled spring 38 secured to the framework of the machine and to the control rod 38, as shown in Fig. 14, tends to hold the rod in its. rearward position, which is the positionof the rod shown in Figs. 1 and 10.

The mechanism which automatically releases the supporting link 40. from the lug 42 and causes the operating rod 38 to drop is governed by other mechanism mounted on the top of the machine frame. The spur wheel 44 is mounted above the frame in the path of movement of the hay which is being pressed in the baling chamber, the direction of movement of this spur wheel being. as indicated by the arrow in Fig. 1. The movement of the spur wheel is transmitted through gears 45 and 46 (see Fig. 3) to the shaft 47. The cam 48 is fixed upon shaft 47, this cam being of the shape shown in Fig. 1. The weighted lever 49 is piv oted on the cam at 50. As the spur gear 44 is actuated by terial through the baling chamber, the cam clock-wise direction until the lug 51 on said cam strikes the lever 49 and carries the same along with it, continuing that motion until the lever strikes the end of a horizontal spring pressed push 'rod 52,forcing it toward the left, as viewed in Fig. 1, and pushing the supporting link 43 off the lug 42. This causes the link 40 and its supported operating rod 38 to drop until the outer end of the rod drops down into its lower position. Let us now turn to Fig. 10 in which the o erating rod 38 is shown in full lines in its rearward suspended position and in dotted lines in its forward lower portion.

A plate 53 is carried by the rod 38 just at the rear of the bend 39. The bell-crank lever 54 is pivoted .to the plate 53. A dog 55 is pivoted to the plate at 56'and is normally. held in a vertical position by'the spring 57 connected at one end to the bell crank lever 54 and at the other end to an extension on the dog 55. crank lever and the dog into engagement with each other at the point 58. as clearly illustrated in Fig. 10. A second dog 59 is pi oted to the plate 53 at 60 and is free to swing forwardly, that is. to the right,as viewed in Fig. 1O. A lug 61 carried by the plate 53 prevents the dog 59 fromswinging rearwardly. The plate "53 has a downlug 62. A pawl 63 is pivoted at 64 to the movement of the ma locked against This spring forces the bell-- the. frame-work of the press with its hooked end urged upwardly by the weight at its Fig. 5, the plunger 21 is provided at one side with a transverse lug 66. This lug is indicated in full lines in Fig. 10, the plunger being omitted so as not to obscure the figure. The lug 66 is accommodated in a slot 67 in the side of the frame-work, this slot being indicated in dotted lines in Fig. 10, no part of the frame-work being shown.

When the operating rod 38 is in its normal or elevated position. the lower ends of the dogs 55 and 59, and the projection 62 are out of the at-h of movement of the lug 66. Now let it be assumed that the supporting link 40 has been released from its supporting lug 42 and that the operating rod 38 is therefore in its lower position. This position of the rod is its rearward lower position. This distinction is made because, aswill presently appear, there is a forward lower position which the rod will assume. If, when the operating rod 38 is dropped to its rearward lower position, the next movement of the plunger is the return or rearward stroke, the lug 66 will strike the projection 62 and the dog 59 and will slightly raise the forward end of the rod. This movement, however, is insufficient in extent to raise the link 40 into engagement with the supporting lug 42, and, as soon as the lug 66 has passed the projection 62 and the dog 59, the operating rod 38 willfall back to its lower position. Further movement of the lug 66 brings it in contact with the rounded end of the dog 55 which yields to let the lug pass by.

When the plunger moves forwardly while the operating rod 38 is in its rearward lowerposition, the lug 66 first encounters the dog 55. As this dog does not swing forwardly, the operating rod 38 will be carried along by the plunger until the bell-crank lever 54 strikes the stationary lug 68 carried by the frame-work. When this happens, the horizontal arm of the bell-crank 54 is tripped up, out of engagement with the dog 55, and the latter is swung to the position indicated in dotted lines, Fig. 10. The projection 62 on the plate 53 is then in'engagement with the pawl 63, and the operating rod is thus rearward movement. The plunger, however, is free to continue its compression stroke. Fig. 10 shows in dotted lines this forward lower position of the operating rod. When theoperatingrod 38 is thus moved forwardly by the plunger, it serves to throw into action the clutch mechanisms connected with the cam disks 22 and 3 to the extent of swinging the bell cranks 35 about their axis 36 and so pulling downward on the links 35 and bringing the extending arms 34 into yielding engagement with t e cam faces-12 and 13 on the large gear wheels 10 andll. Then, as soon as other end. As seen intween the continuously moving rollers 27 i and the adjacent crank disk. The cam -rnit this movement of openings are so placed with respect to one another that, first, the needle operating clutch is thrown in to swing theneedles forward to inclose the bale with wire, and then the twister crank disk 22 is turned to twist the wire'and to'cut it, and finally the needle disk is again rotated throu h a half revolution to withdraw the need es to their initialor idle position. Itwill thusbe seen that the plunger automatically throws. into operation the needle mechanism and the twister mechanism when the bald under formation has reached a predetermined size. The construction and operation of the wire feeding mechanism and 'oof thewire twisting mechanism will nowbe described.

The needle operating cam disk 23 carries a crank pin 69 on which is pivoted the connecting rod 70 as shown in Fig.- 2. At its other end, the connecting rod 70 is pivotally connected with a crank arm 71 fixed upon the vertical shaft :72. This connection .is best shown in Fig. 7" which illustrates the wire feeding needles in detail.

in the particular embodiment illustrated in the drawings, two wire feeding arms or needles are shown, but it isobvious that the number may be varied to suit circumstances, two wires being suficient for ordinary bales. To the vertical shaft 73, positioned at the side of shaft 72, are fixed the curved links 74:, one for each needle. Fixed upon the shaft72 is a curved link 75. The links 74 and 75 are pivoted at their outer ends to the needle or wire feeding arm 7 6. The inner curved end of this arm 7 6 carries a pair of rollers'or sheaves 7'! between which the wire passes and by which it isheld. Normally, the wire feeding arms are in the position shown in full lines, Fig.7, with. the wire passing over and between the sheaves 7? and then outward over a small shcavecarried at the end of link it. When the connecting rod 70 is moved from its extreme left positoin, as shown in Fig. 2, to its extreme crank 71 is pulled forward and the links it and "(5 swing inward toward the framework, and carry the pair of needles 76 through slits in the frame-work and across the baling chamber. The horizontal slits 21' in the plunger, as shown in 4t, perthe wire feeding arms across the baling chamber, it being understood that the needles are advanced into the plunger while it is movin forward to comlete its compression stro e. Fig. 7 shows 1n dotted lines the position which the needles right position, the

anism and toward thedischarge en -n'when at the end oftheir forwarder wire. feeding movement.

- The wire twist to tea their connecting links,

mg and cutting mechanism is arranged -opposite to the wire feeding mechanism on the other side of the machine as is illustrated in Fig. 1. The wiretwisting disks are shown in detail in Figs. 8 and 9 and reference will first behad tothese figures. On the side of the framework are journaled two wire twisters, one for each wire feeding needle or arm.- Each twister comprises a toothed disk portion 7 8 and a locking portion 79, the locking portion being shown in the drawings as rectangular in form. The hub portion 80 of. the twister affords means for-journaling the same in the frame-work. The twister 1s provided with a radial slot 81 which is narrowed toward vits inner half tothe width of one wire so that the wires cannot passeach other as the twister is rotated thereby insuring the opposite twist of the wire at both ends of the twister. The relative position of the twister on theframe-work is shown in Fig. 1. A double rack-bar 82 is adapted to reciprocate between the twisters and is so arranged that the teeth on the bar engage the teeth on the associated twisters. Normally, however, the twisters are locked by the engagement of theirrectangular portions 79 with guide extensions 83 and 83 carried at the front and rear ends of the rack bar 82. A portion of the extension 83 is indicated diagrammatically in dotted lines in Fig; 9 underneath the locking portion 79. So long as the guide extensions 83 engage the locking portion 79 of the twisters as shown in Fig. 1 the twisters cannot be rotateds. The teeth on the rack-bar 82 do not come into engagement; with the twisters until these extensions have moved out of engagement with the locking portions ofthe twisters. Reciprocation of the rack-bar 82 is effectedby a connecting rod M which is pivotally connected at a crank pin 85 to the crank disk 22. When, therefore, the crank disk 22 is operated by its clutch mechanism, the connectingrod 84 will actuate the rackbar 82 either forwardly orbackwardl to operate the, twisters, the rack-bar ma 'ng one complete twisting movement either forwardly or backwardly for eachhalf turn of the crank disk 22.

The position andmovements of the baling wires in the twisting and feeding mechanisms will now be explained. Referring to Fig. 1, two wire: drums 86 and 87 are mounted upon the lower side member of the frame so as to rotate on horizontal axes turning freely thereon each independently of the other. This pair of drums is mounted on the sameside as the wire twistin mechof the machinea Referring to Fig. 2, the wire too lld

side as the wire feeding mechanism and. 1 toward the delivery end of the machine The wire passing from drum 88 is indicated by. the reference numeral 90 and may be called the upper baling wire. The lower baling wire 91 extends across between the other drums 89 and 87,

The operation of the drums during the formation of the bale may be explained as. follows: Each balingwire really consists of two wires tied together at their free ends while the other ends of the wires remain= wound upon their respective drums. Thus,

the upper baling'wire 90 is paid out simultaneously at both ends from the drums 86.

and 88 as the balin larly the lower be from the drums 87 This arrangement of a drum for each end of the baling wire accomplishes several imincreases in size. Simiportant objects. In the first place, it gives to the wire a yieldable support at the side of the machine where the twisting mechanism. is located, so as to cause the wire to be paid out in sufiiclent quantity during the twisting operation, for during that "operation it is essential that a certain amount of wire be paid out in order to allow the twisting to.

take place properly. Without this yielding connection the wire is likely to break during the twisting. Another obgect accomplished by this arrangement of the wire drums is;

the automatic threading of the machine after each bale is complete. In first threading the machine, the ends of the wires from corresponding drums on opposite sides of the machine are threaded through the needle arms and twisted together leaving the wires stretched across the baling chamber. After this initial threading, the machine does its own threading automatically, that is to say after a bale has been formed and the cutting mechanism has severed the twisted wire (as will be more fully explained hereinafter) the wires are left stretched across the baling chamber just as they were when tied together after the initial threading. This automatic threading does away with waste of wire since the cutting mechanism severs eachwire at a point between the two twists. One of these. twists is on the wire around the bale while the other twist holds together the ends of the wires coming from the drums,

As the hay or other material is fed into the chamber and there compressed, the wires are paid out from the drums, and when the bale has reached its proper size the wires will extend longitudinally of the chamber at the sides of the bale. At this stage of the wire feeding, arms or needles 76 are thrust across the baling chamber through the slots ing wire 91 is paid out. and 89 simultaneously.-

' the cutting device.

in the forwardly moving lunger and carry the wires into the slots oi the twister disks so as to form two closed loops of the wire around the bale. Then the twisting mechanism is set into motion through operation of its clutch released by the cam face 13 on the gear wheel 11 and the twisters are rotated as previously described to twist the wires. The result of this twisting operation is indicated in Fig. 9. It should be remembered that the feeding and twisting operations occur while the plunger is near or at the end of its compression stroke. In this way the bale is wired more securely than if the operations occurred while the plunger was removed from the bale for that would give the bale a chance to expand before the twisting had been completed.

The twister crank disk 22 makes but one half revolution during each twisting opera tion, that movement of the disk being intermediate in time between two corresponding half revolutions of the opposing crank disk of the needle mechanism. During the first half revolution of the needle disk 23 the wire feeding arms or needle 76 are carried across the baling chamber through the slots in the plunger and over to the wire twisting disk. After this has taken place, the gear 11 is in such position that the extending arm 34 can drop down into the slot 14 thereby rcleaslng the latch of the clutch and connects in the twister crank disk 22 with the continuously rotating shaft 25 (Fig. 18). This rotates the twister crank disk through an angle of 180 degrees thereby thrusting the rack 82 forwardly to operate the twisting disks and As the operation of the machine continues the rack-bar 82 remains in its forward position for by that time the opening 14 has moved past the arm 34 and the swinging clutch arms 31 and 32 have moved inward to engage the latch 28 thereby disconnecting the cam disk from 1ts drive shaft. After the nextbale has been formed and the needles have been advanced into twisting position, the twister clutch Wlll again be thrown in and will efiect another half revolution of the twister disk 22 thereby withdrawing the rack-bar 82 from its forward position to the position shown in Fig.

1. During this rearward movement the w re twisting disks are again. operated to twist the baling wires.

The cutting device is operated by the rackbar and severs the twisted wires at a oint between the two twists whichere ma e on opposite sides of each wire twisting disk as best shown in Fig. 9. In the form shown in the drawings the cuttin devlce consists of a vertically movable kni e 92 which cooper ates with the face of the twisters to cut the wires. The knife is at its upper end connected with a bell-crank 93 by a slot and pin connect-ion this bell crank being pivoted to the frame-work at 94 and at its other end carrying a lug 95 which'is in the path of movement of stops 96 and 97 carried on a horizontal bar 98 mounted at the side of the twister rack, these stops 96 and 97 being adjustable along said bar to vary the timing of the cut. From this it will \be clear that as the rack-bar approaches the limit of its forward movement the stop 97 strikes the lug 95 swinging the bell-crank 93 and shifting the knife 92 downwardly to sever the twist ed wires. Fig. 15 shows the knife 92 in perspective and 9 clearly shows the cutting notches 92 and 92". When the knife is moved downward at the end of the forward movement of the rack-bar 82 one set of notches will sever the twisted wires and on the next succeeding movement of the knife tion to the needles 76 sheaves 101 (Fig. 3)

are fixed on the swinging links 74. The folding character of the needle. carrying structure is such that on forward movement there is substantially enough slack in the wire to supply all the wire necessary for bridging the baling chamber. The needle movement may therefore be rapid and without danger of rupturing the wire through the inertia of the wire carrying spools. It is on the return movement of the needles that the greater part of the unwinding of new wire takes place, The return movement of the wire feeding needles takes place, as herebefore explained, after the twisting operation has been performed and is timed.

, by the clutch'mechanism at the other end of the machine working in conjunction withthe cam flange 12 carried on the large gear wheel 10.

0n the return movement of the plunger after the wire feeding and twisting operations have been accomplished the operating rod 38 is restored to its normal or raised position. It will be remembered that when the plunger begins its return movement after the bale has been completed the operating rod 38 is in the position indicated in dotted.

lines in Fig. 10. When the extension 66 on the plunger strikes the dog 59 the operating rod is raised because the dog is prevented from yielding rearwardly' because of, the stop 61. This lifting of-the operating rod raises the projection 62 out of engagement withthe locking pawl 63 while the supporting link -40 will be raised suficiently to hook ipraaae over the lug 4L2 (through the action of r r 40) into position tosupport the weight o: the operating rod 38. As soon as the looking engagement between the projection 62 and the pawl 83 is broken as above described the spring 38 draws the operating rod 38 'rearwardly to its original position. This rearward movement swings the bell cranks 36 of the clutch mechanism moving the links 35 upwardly and thereby releasing the pull on the arms 34 and allowing them to lift slightly out of engagement with their respective cam faces carried at the sides of the large wheels 10 and 11. This disconnects the feeding and twisting clutches and allows the machine to complete the construction of another bale while the needles-and the twisters remain idle.

Positioned immediately in front of the forward end of the operating rod 38 is a pivotally mounted platform 102 having at its rear'end a pivotal connection with a vertical link 1108 which extends upwardly along side of the supporting link 40 and is pivoted to a swinging lever 104 mounted on the side of lug 42 and so positioned that it can lift a projecting finger vertically between the lug 12 and the projection 43 on link 40 thereby preventing engagement of the part 13 with the lug for such time as the platform 102may be in its depressed or tilted position through pressure thereon of the forward curved end of the operating rod 38. It is the function of this group of elements to prevent latching at the lug 42 during the first return movement of the plunger which follows the release or dropping of the operating rod 38 when the bale has reached full size. In other words even though the lug 86 on its return movement may strike against the dog 59 and lift the operating rod 88 temporarily, there can be no engagement with lug 42 because of the intervention of the finger actuated from the rocking platform 102. The next forward movement of the plunger slides the front end of the operating rod 38 across the platform 102 and tilts it back to its initial hori zontalposition thereby pushing upward on link 103 and withdrawing the finger carried by lever 104: putting the parts in such relation that the next return movement of the plunger will lift the operating bar under such conditions that it can be retained in that raised position and can be pulled back by itsv main retraction s ring 38' into its initialor raised rearwar position.

The packing lever used for packing the hay or other material in the baling chamber is best shown in Fig. 6. The packing lever 105 is angular in shape and carries a head 106 in position to swing down into the hop per 107 in advance of the forward movement of the plunger 21. The curved lever 105 is journaled in a pair of brackets 108 mounted on the top of the machine and has its lower end'pivotally connected to a link 109, this link being pivoted to the-plunger rod 20 lVhen the plunger 21 is in its compressing position the packing lever is in a substantially upright position as indicated in full lines in- Fig. 6, but during the return movement of the plunger, the lever is swung down to push the material through the hopper into the compression chamber and assumes the position indicated by dotted lines in Fig. 6.

An adjustable compressing device or press is mounted at the outlet end of the machine to govern the size of the delivery opening and thereby togovern the degree of compression in the bale. This press is shown somewhatdiagrammatical in Fig. 21, and comprises: tension bars 110' and 111 carrying the cross-piece 112 at the bottom, this oiece fitting under the lower platform 113 and lower side rails 114 of the chamber through which the bales pass out. A similar cross-bar 115 receives the rods 110' and 111 through its ends and carries at its center an upstanding screw-threaded stud 116 provided with a handle 117 whereby the crosspiece 115 may be forced away from the cross-piece 118 to which rods 110 and 111 are anchored. This separation of the crosspieces 115 and 118 serves to spring together the top and bottom of the bale chamber thereby narrowing the opening through which the bale must pass ano so offering greater resistance to the plunger and thus efiecting greater compression of the materials in the baling chamber. Side plates the cross-pieces 112 and 115 so that the approach of these cross-pieces toward one another will simultaneously effect an inward movement of the members 119 thereby effecting compression at the sides of the bale simultaneously with compression in a vvertical direction. i
